For pirates and the regulars of tattoo salons, the skull is the symbol of ruthlessness. Some bikers even believe that having an image of the skull may let you fool Mrs. Death. But if you ask a doctor they will tell you that a human skull of an adult is nothing but a complex of 22 bone elements (although it is 44 at the moment of birth, huh). Doesn't that make it a perfect puzzle to assemble?
